Swiss watch manufacturer Breitling sponsored a restoration of a C-121C Super Constellation, registration N73544, that is based in Basel (Switzerland) and has since been featured in its advertisements. This plane is now registered in the Swiss Aircraft registry as HB-RSC.

The Lockheed L-1049 Super Constellation is an American aircraft, a member of the Lockheed Constellation aircraft line. The L-1049 was Lockheed's response to the successful Douglas DC-6 airliner, first flying in 1950. The aircraft was also produced for both the United States Navy and Air Force as transport and AWACS aircraft. The USAF had also ordered 33 L-1049F Super Constellations in 1951, designated the C-121C. Unlike its Naval equivalent, the C-121C featured square cabin windows instead of round ones. The C-121C also featured a reinforced structure to handle turboprop engines if necessary. Other features of the C-121C included an Auxiliary Power Unit Turbo-compound R-3350s and the ability to carry 75 passengers, 72 fully equipped troops, or 47 stretchers. The seats could be stored under the floor of the aircraft when needed for cargo use. The first flight of a C-121C was in 1955. After military service, some C-121s were used by civilian operators as cargo aircraft. Two former C-121Cs fly today with the Historical Aircraft Restoration Society of Australia and the Super Constellation Flyers Association of Switzerland.
